  2. 16. Viruses as a Model System for Studies of Eukaryotic mRNA Processing

    Author : Anette Lindberg; Jan-Peter Kreivi; Göran Akusjärvi; Lars Wieslander; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; ICP27; herpes simplex virus; mRNA; splicing; adenovirus; ASF SF2; Molekylärbiologi; Molecular biology; Molekylärbiologi; Medical Virology; medicinsk virologi;

    Abstract : Viruses depend on their hosts for the production and spread of new virus particles. For efficient virus replication, the viral genes have adapted the strategy of being recognized and processed by the cellular biosynthetic machineries. Viruses therefore provide an important tool to study the cellular machinery regulating gene expression. READ MORE

  4. 17. Hyaluronan receptors of liver endothelial cells, their purification and characterisation

    Author : Peter A. G. McCourt; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; hyaluronan; scavenger receptors; ICAM-1; liver endothelial cells; Biokemi; Biochemistry; Biokemi; fysiologi; Physiology;

    Abstract : Hyaluronan (HA) is a polysaccharide common throughout the connective tissues. and is found at low concentrations in the blood. The major site of its clearance is via an endocytic receptor on liver endothelial cells (LEC). This process is vital, as excessive serum levels of HA lead to clotting disorders and overly viscous blood. READ MORE

  5. 18. Molecular Cloning and Functional Characterization of Factors Involved in Post-transcriptional Gene Expression

    Author : Shao-Bo Jin; Lars Wieslander; Maria Carmo-Fonseca; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gene expression; pre-mRNA processing; pre-rRNA processing; Molecular biology; Molekylärbiologi;

    Abstract : Gene expression in the eukaryotic cell is a fundamental cellular process, which consists of several distinct steps but extensively coupled to each other. From site of transcription in the nucleus to the cytoplasm, both mRNA and rRNA are associated with a proper set of proteins. READ MORE

  6. 19. Biogenesis of messenger and ribosomal RNPs in the eukaryotic cell

    Author : Petra Björk; Juan Valcárcel; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi; Physical Biology; fysikalisk biologi;

    Abstract : In eukaryotic cells, gene expression involves multi-step processes in the nucleus and the cytoplasm. The different processes engage specific RNA-protein complexes, RNPs. Upon activation of most, if not all genes, a precursor RNA molecule is synthesized that has to be extensively processed and modified. READ MORE

  7. 20. Biochemical and structural studies of pre-mRNA splicing

    Author : Ingela Wetterberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Gene expression; pre-mRNA processing; transcription; in situ; electron tomography;

    Abstract : When eucaryotic genes are expressed, they are transcribed into pre-mRNAs (precursor mRNAs) that need extensive processing before they can be exported from the nucleus as mRNAs and translated into proteins in the cytoplasm. One central processing event is splicing, which means removal of intervening, non-coding sequences, introns and joining of functional sequences, exons. READ MORE
